Desheng Product Tris Suppliers and Manufacturers

The Chinese name of Tris is tris(hydroxymethyl)aminomethane, tromethamine, tromethamine, 2-amino-2-(hydroxymethyl)-1,3-propanediol. It is a white crystal or powder. Soluble in ethanol and water, slightly soluble in ethyl acetate and benzene, insoluble in ether and carbon tetrachloride, corrosive to copper and aluminum, and irritating chemicals. Tris has a high buffer capacity, high solubility in water, and is inert to many enzymatic reactions, making Tris a very satisfactory buffer for many biochemical purposes. It is generally used to stabilize the pH of the reaction system, and has a strong buffering capacity between pH 7.5-9.0. Advantages of Tris buffer: 1. Because Tris base is more alkaline, you can only use this buffer system to configure a buffer with a wide range of pH ranging from acidic to alkaline; 2. It has little interference to biochemical processes, and does not precipitate with calcium, magnesium ions and heavy metal ions. Disadvantages of Tris buffer: 1. The pH of the buffer is greatly affected by the concentration of the solution, the buffer is diluted ten times, and the pH change is greater than 0.1; 2. The temperature effect is large, and the temperature change has a great influence on the pH of the buffer. The pH of the buffer at 4�?�°C is 8.4, and the pH at 37�?�°C is 7.4. It must be prepared at the temperature of use, and prepared at room temperature Tris-HCL buffer cannot be used for 0-4; 3. It is easy to absorb CO2 in the air, so the prepared buffer should be tightly sealed; 4. This buffer has a certain interference effect on some PH electrodes, so use electrodes that are compatible with Tris solution. Application of Tris buffer: It forms a buffer system with glycine in the electrophoresis buffer to stabilize the pH; uses the Tris-HCL buffer system in the gel to stabilize the pH; it is widely used as a solvent for nucleic acids and proteins; the low ionic strength of the Tris buffer can also be used The formation of intermediate fibers of nematodes; add EDTA to Tris hydrochloric acid buffer to make "TE buffer", which can be used for DNA stabilization and storage; change the pH-adjusting acid solution to acetic acid to obtain "TAE buffer", change "TBE buffer" can be obtained as boric acid. These two solutions are used in nucleic acid electrophoresis experiments.

De Sheng is a professional blood testing reagent company. It is a single enterprise with a complete industrial chain in China. Up to now, it has more than 10 years of R&D and production experience. Biobuffer products developed by Liu technical team of the company include Tris, Bicine, Caps, Mops, Taps, EPPS, HEPES, MOPSO, PIPES and so on, which are well received. DeSheng brand Tri (hydroxymethyl) Angelica Tris introduced: Trometamol Name Trimethylol Angelica End Tris CAS# 77-86-1 Molecular Weight]121.135 Molecular Formula Adidine H11NO3 Storage Conditions Room temperature, light-proof and moisture-proof Appearance White Crystal Powder PH Scope] 7-9 Melting Point 168-172 degrees C 1. Dissolve Tris with a small amount of double-steamed water (300-500 ml). After adding HCl, adjust the pH to 7.6 with HCl (1N) or NaOH (1N), and add extra-thick double-steamed water to 1000 ml. This liquid is a reserve liquid, which is stored in refrigerator at 4 C. Uses: Buffer preparation in biochemical and molecular biology experiments; intermediate; preparation of surfactants and vulcanization accelerators; preparation of water-soluble polymers containing Tris structural units as paint dispersants; preparation of indoor formaldehyde adsorption materials, etc., Tris is also used as titration standard. 1. Buffering properties] Tris is a weak base, and its pKa is 8.1 at room temperature (25 C); according to the buffer theory, the effective buffer range of Tris buffer is between pH 7.0 and 9.2. Desheng products include good's buffer: Bicine, Caps, EPPS, MOPS, TAPS, HEPES, MOPSO, PIPES; blood vessel extracting additives: serum separating gel, sodium glycerin, glycerin, EDTA dipotassium, EDTA tripotassium, coagulant, planning agent, sodium citrate, planning potassium; chromogenic substrates: TOOS, TOPS, ADOS, ADP S, ALPS, DAOS, HDAOS, MADB, MAOS, PEP, etc. Luminescent reagents: Azidine ester, Luminol, Azidine salt and isoluminol. All in vitro diagnostic reagents are purified by HPLC analysis method and the purity is more than 99%. As the manufacturer develops and sells, the DeSheng color substrates are in stock and the quality is guaranteed. Enterprise friends who need color raw materials can contact Desheng, address C8, Guanggu United Science and Technology City, Ezhou, Hubei Province, and look forward to your visit!
